Dr. Best has successfully used his skills as a CTO, Senior Scientist, and as an Executive Engineering Leader to successfully solve problems throughout his career, which began working in the vacuum tube industry. Designing and fabricating any vacuum tube requires a knowledge of particle physics, material science, electromagnetic wave propagation, vacuum technology, and heat transfer, so it is a combination of all classical sciences combined into one application. As commercial and military applications for vacuum tubes diminished, Dr. Best developed solid-state amplifiers and oscillators for applications. This work diversified into the development of integrated antennas, low noise amplifiers, filters, mixers, transmissions lines, couplers, and any number of components necessary to build systems up to 300 GHz. His work in the Terahertz frequency span for JIEDDO enabled Dr. Best to be the founder of the IEEE Transactions on Terahertz Science and Technology.
